  1. 1AlgorithmA process to be followed in problem-solving, usually by computers.
  2. 2AssemblerA computer program which translates assembly language to an object file or machine language format.
  3. 3BandwidthThe frequency that a particular signal is transmitted at.
  4. 4Bespoke SoftwareSoftware that is specifically developed for a specific organisation/user.
  5. 5CPUCentral Processing Unit - Most processes take place here - the brains of a computer.
  6. 6Cache MemoryAn auxiliary memory from which high-speed retrieval is possible.
  7. 7Client-ServerA computer system in which a central server provides data to a number of networked workstations.
  8. 8ClockspeedThe number of calculations a CPU can do per second.
  9. 9CompilerA computer program which translates source code in a programming language into another computer language.

  21. 21Internal StorageThe computer's internal hard drive - Primary storage device.
  22. 22InterpreterA program that can analyse and execute a separate program line by line.
  23. 23LANLocal Area Network - Connects devices in a relatively small area.
  24. 24Loss-lessWithout loss of information.
  25. 25LossyWhere unnecessary information is discarded.
  26. 26MAC AddressA unique identifier assigned to network interfaces.
  27. 27Machine CodeA programming language consisting of binary or hexidecimal instructions.
  28. 28Magnetic StorageStorage which uses different patterns of magnetisation to store the data.
